ELECTRIC DRAIN VALVE

PRODUCT DESCRIPTION

The Electric Drain Valve removes condensed water and oil from the
moisture sepearator. Additional drains may be installed throughout your
compressed air system, including aftercoolers, filters, drip legs and
dryers.
The Electric Drain Valve operates on a timer which can be set to
automatically drain the air receiver tank at operator–determined
intervals.
Key features include:
• 100% continuous duty
• NEMA 4 enclosure
• Adjustable time on (0.5 – 10 seconds)
• Adjustable time off (0.5 – 45 minutes)
• Stainless steel operator
• LED to indicate electrical power is on
• LED to indicate valve is open
• Manual override
OPERATION
1. Open the strainer ball valve.

OPEN
2. Set the "time off" and "time on" knobs. See TIMER SETTINGS
(below) for an explanation of the settings.
3. During compressor operation, check for air leaks.

TIMER SETTINGS

The "time off" setting determines the interval between cycles from 30
seconds to 45 minutes. The "time on" setting determines the actual time
the compressor drains condensate.
The timer's cycle rate and drain opening time should be adjusted to
open just long enough to discharge the condensate. The timer is
properly set when it opens and discharges condensate and then vents
air for approximately one second before closing. Adjustments may be
made depending on many factors, including humidity and duty cycle.

ACTION
1. Remove solenoid
valve, disassemble,
clean and reassemble.
2. Check and replace

activate supply.
2. Timer malfunction
3. Clogged port.
4 Solenoid valve
malfunction.
5. Clogged strainer.
MAINTENANCE
Periodically clean the screen inside the valve to keep the drain
functioning at maximum capacity. To do this, perform the following
steps:
1. Close the strainer ball valve completely to isolate it from the air
receiver tank.
2. Press the TEST button on the timer to vent the pressure remaining
in the valve. Repeat until all pressure is removed.
CAUTION! High pressure air can cause injury from flying debris.
Ensure the strainer ball valve is completely closed and pressure
is released from the valve prior to cleaning.
3. Remove the plug from the strainer with a suitable wrench. If you hear
air escaping from the cleaning port, STOP IMMEDIATELY and repeat
steps I and 2.
4. Remove the stainless steel filter screen and clean it. Remove any
debris that may be in the strainer body before replacing the filter screen.
5. Replace plug and tighten with wrench.
6. When putting the Electric Drain Valve back into service, press the
TEST button to confirm proper function.
